David Toms is looking forward to ending his season on a high note after getting an 11-hour call-up for next week's Grand Slam at Port Royal Golf Course.

The American has been drafted in to replace Louis Oosthuizen, who withdrew yesterday after failing to recover from an ankle injury he sustained while hunting in South Africa two weeks ago.

Toms, who won the PGA Championship in 2001, has not had a bad year so far. He finished in a tie for third at The McGladrey Classic on Sunday and is 48th on the PGA Tour's Money Leaders list.

"I'm excited to be a part of the PGA Grand Slam of Golf, I've played in it before, and it's a great event," said Toms. "The PGA of America is a wonderful organisation and they run incredible tournaments.

"I've never been to Bermuda, so I am looking forward to going and playing against Ernie (Els), Martin (Kaymer) and Graeme (McDowell). It will be a great way to end my 2010 season."

Toms' only other appearance in the Grand Slam came in 2001, when he finished second behind Tiger Woods. And while he may not have won a major since then, the three-time US Ryder Cup team player has been a consistent performer year-on-year.

"David Toms is a past major winner, he's had a great season in the majors this year, 14 (Masters), 33 (US Open), 33 (PGA Championship), and we're looking forward to having him," said David Charles, the PGA's senior director, championships.

With Martin Kaymer, Ernie Els, and Graeme McDowell the rest of next week's foursome, Toms will have his work cut out to equal or better his previous Grand Slam showing.

Kaymer's victory in the Alfred Dunhill Links Championship on Sunday will propel him to fourth in the world, and was his third consecutive European Tour win, something not achieved since Nick Faldo won the European PGA, British Masters and French Open titles in 1989.

And his Ryder Cup captain Colin Montgomerie was only half joking yesterday when he said that the German could end up beating Lee Westwood to the world's number one spot.

"If (Kaymer) continues his way, he'll probably beat Lee Westwood to (number one) if he keeps winning," said Montgomerie.

Oosthuizen's withdrawal had seemed likely after he sustained ligament damage to his left ankle during a hunting accident in South Africa two weeks' ago, while celebrating the wedding of fellow European Tour professional Charl Schwartzel.

Having already pulled out of last week's Alfred Dunhill Links Championship, Oosthuizen had hoped to be fit in time to play in this week's Portugal Open. That though proved beyond him, and he told PGA officials yesterday that he would not be able to play in Bermuda.

With only former major winners eligible to be chosen for the event, Toms, who was the fifth alternate, was handed the vacant spot after Retief Gosen and Zach Johnson both declined the invitation to play.

"Retief Gosen is in Singapore and he can't physically get here (Bermuda) in time," said Charles. "He can only get here on Monday afternoon, and we have too many obligations with the Golf Channel clinic, and the Pro-Am, so he couldn't make it.

"And Zach Johnson has just got off the road from a busy schedule, Fed-Ex Cup, Ryder Cup, and he has a seven-week old baby, who he has only seen for a week, so he's tired and wants to see the family."

McDowell will arrive tomorrow, with the rest of the players flying in over the weekend, while PGA officials are already at Port Royal preparing for the start of the event, and television station TNT are also getting themselves ready. The course though is not something they need to worry about.

"The circus has arrived," said Andrew Brooks, Port Royal's director of golf, "but you could put the golf course against any other course in the world right now, and it'll be as good as, if not better.

"Steve Johnson's team have done a fantastic job to get it looking as good as it does now, and everything is in good shape."
